Electric vehicle charging network services

ABSTRACT

To provide remote services, including dynamic, interactive assistance to electric vehicle (EV) users, a central server is arranged for electronic communications with EVs (15) and with client devices (11). The server also communicates with at least one EV charging station network, which in turn communicate with individual charging stations (30). Remote services may include trip planning, locating charging stations, checking availability and suitability of charging stations, making reservations at charging stations, and updating plans en route. The server collects data from the EV and analyzes the data to determine various statistics. The system advises a user on readiness of the EV to complete a proposed trip before recharging the EV batteries. Client devices may include smart phones, computers, or a head unit in the EV. Application software programs are executable on the client devices to provide user interfaces for accessing the remote services and for communicating with the central server.

TECHNICAL FIELD

This invention pertains to methods and apparatus for networked electricvehicle (EV) user support services.

BACKGROUND OF THE INVENTION

Conventional technical schemes are available for assisting a driver indetermining an appropriate time to “fill up” their vehicle. Theconventional technical schemes typically involve a fuel gauge installedin the dashboard of a vehicle. The fuel gauge may have a full marking,an empty marking, other markings in between, and a needle indicatingcurrent fuel level relative to the markings. The gauge may also includea fuel light to activate when current fuel level reaches a presetfraction of maximum fuel. A driver can use the fuel gauge to determinean appropriate time to “fill up”.

While these conventional technical schemes for assisting a driver indetermining an appropriate time to “fill up” or refuel their vehicle,partially or completely, are typically sufficient for gasoline poweredvehicles, electric vehicle usage is different than gasoline poweredvehicle usage. In particular, electric vehicles considered as a wholetypically have a shorter range (distance between “fill-ups”) thangasoline powered vehicles. Electric vehicles typically require severalhours to recharge, which is longer than the minutes needed to refuel agasoline powered vehicle. Also, electric charging stations are notcurrently ubiquitous (as compared to gasoline stations). In view of theforgoing, a technical solution is needed to assist a driver of anelectric vehicle in determining an appropriate time and place torecharge their vehicle battery.

SUMMARY OF THE INVENTION

The following is a summary of the invention in order to provide a basicunderstanding of some aspects of the invention. This summary is notintended to identify key/critical elements of the invention or todelineate the scope of the invention. Its sole purpose is to presentsome concepts of the invention in a simplified form as a prelude to themore detailed description that is presented later.

In one aspect, this disclosure describes a feature for EV users toreduce anxiety that may be caused by uncertainty as to whether or not anelectric vehicle has sufficient charge to carry out its agenda for theremainder of the day. In other aspects, software analyzes a plannedroute, in view of a variety of information including but not limited toa history of prior usage data for the vehicle, driving style, plannedroute, current traffic conditions, and current charge or energy level ofthe vehicle batteries, to determine whether it will have sufficientrange to complete the proposed trip.

In another aspect, the system provides information to a user regardingcharging stations located either nearby or along a proposed route, forrecharging the vehicle. Range analysis, mentioned above, combined withroute planning and charging station data can be used to identifycharging stations along the route, to check their suitability for thevehicle, to check their availability, and to make a reservation forcharging at a selected charging station.

In a preferred embodiment, some user services and features are providedthrough communications between a “client” device in the car and acentral server computer, further explained below. Preferably, thecentral server is arranged for communication with at least one chargingstation network.

Additional aspects and advantages of this invention will be apparentfrom the following detailed description of preferred embodiments, whichproceeds with reference to the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 1 illustrates a system to assist a driver of an electric vehicle(15). For example, the system can be used for determining an appropriatetime or place to recharge the vehicle battery. The system 100 includes aserver 12, which may comprise one or more servers and other resources,wherever located. It has suitable means for communications over one ormore networks, such as the Internet and/or a telecommunications network.It may communicate via a suitable gateway to a wirelesstelecommunications network. In some embodiments, the wirelesstelecommunications network may be used for server communications with aclient device 11. In some cases, in-band signaling may be used for datacommunications during a voice channel call on the wirelesstelecommunications network. In some embodiments, a broadband or WiFinetwork may be used for server communications with a client device 11.Any or all of the above, as well as a wired network, POTS, cable, orother means not yet known may be used for server communications withother one or more EV charging station networks (not shown), which inturn may communicate with individual charging stations 30.

A client device 11 may comprise, in some embodiments, a personalportable device (cell phone, PDA, laptop, tablet computer, etc.), avehicle “head unit,” a desktop computer, or the like. The servers 12typically include a memory device to store instructions that, ifexecuted by a computing device, perform operations that will bedescribed herein as operations of the server 12.

The server 12 may collect, from an electric vehicle or a computingdevice coupled to the electric vehicle, data for learning drivingpatterns. In a preferred embodiment, the server transmits a query orrequest to a wireless communication device embedded in the EV to acquirehistorical driving data. In an alternative embodiment, a client device11 in or near the EV may be used to acquire the data and transmit it tothe server. The server 12 generates a driving history based on thecollected data. The server 12 may store the driving history in adatabase. The database may be organized, for example, as a plurality ofentries or records, each indicating a particular driving trip of thesubject vehicle. Data may be aggregated over a fleet of vehicles.

A trip record may include, for example, a distance traveled by theelectric vehicle, how much energy was used by the electric vehicleduring the trip, and a time stamp indicating a date and time that thetrip started and/or ended. Additional information in a trip record mayinclude a route, start and stop locations, way points, traffic data andor topological data. It may include weather conditions or temperature,traffic conditions and other variables. A detailed record may includeperiodic speed readings.

The server 12 analyzes the database entries. In one example, the server12 may identify patterns based on the database entries, i.e. adifference between certain days of the week vs. other days of the weeks,which has some consistency across weeks, i.e. observing that 18 kilowatthours are typically used on Wednesday while 15 kilowatt hours aretypically used on a Thursday.

In one example, if a pattern is identified, the analysis may include theserver 12 interfacing with a calendaring application to determine futuretrips that would skew an expected usage based on an identified pattern.The server 12 may check the appointment for address information.However, if the appointment lists a person but not address information,the server 12 may obtain address information listed for the person fromthe appointment using contacts or some other database.

In one example, the server 12 may determine an expected energy usage fora time period to occur based on the analysis. The determination canconsider parameters such as temperature, weather conditions,characteristics of expected travel when they vary from historical travel(such as the use of a hilly route or a high speed freeway that are notnormally used), traffic, tire pressure, vehicle load (number ofpassengers), or other variables. In one example, the determination mayinclude comparing a current or expected temperature for the time periodwith an average temperature based on prior corresponding time periods.Energy usage may be higher than expected from the identified pattern ifthe day is unusually cold, for example, because a driver may be expectedto utilize the vehicle's heater more than usual. Conversely, in hotweather the air conditioning will have a similar impact. HVAC in generalrequires energy from the batteries. Also, weather forecasts or currentconditions can also be used in the determination. For example, expectedenergy usage may be different than expected based on an identifiedpattern if there is currently snow on the ground or other weatherconditions that could affect frictional coefficients of the tires of theelectric vehicle.

The server 12 may generate a presentation for a driver of the electricvehicle based on the determination. The generated presentation is to bedisplayed using the client 11 (in one example the generated presentationmay be displayed on a visual and/or audio display of a vehicle head unitof the electric vehicle).

The generated presentation may indicate whether the amount of energycurrently stored in the battery of the electric vehicle is greater thanthe expected energy usage for a particular time period, e.g. the rest ofthe day, based on the determination. In one example, the generatedpresentation specifies that the driver is “Ready To Go”™ (“Ready to Go”is a trademark of Airbiquity Inc.) if the amount of energy currentlystored in the battery of the electric vehicle is greater than theexpected energy usage for the rest of the day. In an embodiment thedetermination may be made not for the whole day, but for the morningcommute to work, for example, or return home from the office. A screenfor the example described in the immediately preceding paragraph isshown in FIG. 3. The shading extending from 0 to below 50% representsthe determination of energy usage for the day. The dial indicates energyavailable in the battery.

FIG. 2 is an example of a screen display for login to a clientapplication consistent with the present disclosure. In this example, thelogin screen is shown for a smart phone type of portable device.Suitable applications or “apps” may be provided for various differentclient devices as noted, and a similar application may be deployed on avehicle head unit. In FIGS. 3-53, a smart phone or iPhone display screenis used by way of illustration and not limitation. Any display,including a windshield “head up” display, may be used.

Referring again to FIG. 1, the server 12 may store an application 20 tobe downloaded to a personal portable device for operation thereon. Inone example, the application 20 is downloaded to a personal portabledevice, such as a mobile phone. The personal portable device operatingthe application can remotely control a component of the vehicle.

In one example, the downloaded application causes the screen shown inFIG. 3 to be displayed on the personal portable device. The “charge nowbutton” causes the personal portable device to transmit a signal thatcauses the electric vehicle to begin charging (so long as the electricvehicle is plugged in to a utility power source). Other components ofthe vehicle may be controlled using the Remote Control feature furtherdescribed below.
